Character position definition and scope:

The Multipart resource record level character position contains a one-character code that indicates the record level to which a resource pertains and any record dependencies.  This information will facilitate processing the record in different situations.  For example, the record may describe a set of items, or it may describe a part of a set.  The part may only have a dependent title to be used for identification purposes thus requiring use of additional information to understand its context.
